C# connection string in web.config file

Question

In my code behind page, how do I access the connection string which is stored in my web.config file?

Answer 1

System.Web.Configuration.WebConfigurationManager.ConnectionStrings["YouConnStringName"].ConnectionString;

This requires references to System.Configuration.dll and System.Web.dll.

Answer 2

How to: Read Connection Strings from the Web.config File

Answer 3

From comment on http://msdn.microsoft.com/en-us/library/ms178411.aspx

string c = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["myconnectionstringname"].ConnectionString;

Requires your project to reference to System.Web and System.Configuration. I had to actually add a reference to "System.Configuration" not just add a Using.
